MOTOR-CYCLE FRAME.

SPECIFICATION forming part of Letters Patent No. 696,001, dated March25, 1902. Application filed July 6, 1901- Serial No. 67,262. (No model.)

To all whom it may concern.-

Be it known that I, VINCENT H. BENDI X, a citizen of the United States,and a resident of the borough of the Bronx, New York city, New York,have invented certain new and useful Improvements in Motor- CycleFrames, of

which the following is a specification.

My invention relates to an improvement in motor-cycle frames, wherebythe vibration caused by the motor is taken up and the objectionsheretofore existing to motor-cycles on this account largely done awaywith. The constant vibration caused by the motor is exceedinglyunpleasant and in a rigid construction of frame, as heretofore,unavoidable. By my improvement I have produced a frame especiallyadapted for the seating of a motor, and with its members so connectedthat the vibration communicated from one to the other thereof isminimized.

I shall describe a structure embodying my invention, the featuresthereof being more particularly pointed out hereinafter in the claims.

The drawing shows a motor-cycle frame illustrating my improvement inside elevation.

a indicates the seat-post, and Z) the head; 0, the top bar, and d thebottom bar connecting the seat-post and head, the bottom bar andseat-post being held in crank-bracket e, as shown, the wholeconstituting the front member of the frame.

f indicates the top rear bar, and g the bot tom rear bar, the bars beingconnected at one end to the fork end and at the other to a crossbar h,the whole constituting the rear member of the frame. The bar it forms amotorsupport and is preferably curved forward at the bottom to form aseat for the motor, which may be attached thereto by any convenientmeans, such as by straps or bands 2' 2' i i. The front and rear membersare connected by means adapted to confine the vibration of the motor tothe rearmember, such as springs j and 7c, spring j being preferaby ofthe cushion-spring type, pivoted at one end on bar h and at the other onseat-post a, and spring 7.; being of any convenient type or a simplemovable joint connected at one end to the bar It and at the other to thecrank-bracket'e.

The front member of the frame is preferably rigid in construction, andthe top and bottom rear bars are preferably rigidly connected to the barit, thetwo members being connected together by springs or by a springand a movable joint adapted to confine the vibration of the motor to therear member thereof, as stated.

It is obvious that various types of connecting springs or joints may beused and that the form and shape of the members may be varied withoutdeparting from the spirit of my invention, and I do not desire torestrict myself to the details shown.

What I claim, and desire to secure by Letters Patent, is-

l. A motor-cycle framehaving a front member provided with a seat for therider and a rear member provided with a motor-support, the front andrear members being connected by means adapted to confine the vibrationof the motor to the rear member.

2. A motor-cycle frame having a front member provided with acrank-bracket and with a seat for the rider and a rear member providedwith a motor-support, the front and rear members being connected bymeans adapted to confine the vibration of the motor to the rear member.

3. Amotor-cycleframehavingafrontmember provided with a seat for therider and a rear member having its fork ends connected by bars to across-bar adapted to form a motor-support, the front and rear membersbeing connected by means adapted to confine the vibration of the motorto the rear member.

4. A motor-cycle frame having a front member provided with a seat forthe rider and a rear member having its fork ends connected by bars to across-bar turned up at the bottom to form a seat and support for themotor, the front and rear members being connected by means adapted toconfine the vibration of the motor to the rear member.

5. Amotor-cycle frame havingafrontmember consisting of a head, seat-postand connectingbars held in place on the crankbracket, and a rear memberconsisting of top and bottom bars connected to the fork ends and to across-bar turned up at the bottom to form a seat for a motor, the frontand rear members being connected by springs connecting the motor-supportand the seat-post at the top and the motor-support and the crankbracketat the bottom, substantially as described.

6. A motor-cycle frame havinga front member consisting of a head,seat-post and connectingbars held in place on the crankbracket and arear member consisting of top and bottom bars connected to the fork endsand to a cross-bar curved forwardly at the bottom to form a seat for amotor, the front and rear members being connected at the top by acushion-spring pivoted at one end on the motor-support and the other onthe seat-post and at the bottom by a spring connected at one end to theforwardly-curved portion of the motor-support and at the other to thecrank-bracket; substantially as described.

7. A motor-cycle frame havingafront rigid member provided with a seatfor the rider and a rear rigid member having its fork ends secured bybars to a cross-bar forming a motorsnpport, the rigid members beingconnected by means adapted to) confine the vibrations of the motor tothe rear member.

I 8. Amotorcycle frame havingafrontmembor provided with a seat for therider and a rear member having its fork ends connected by bars to across-bar adapted to form a motor-support, the front and rear membersbeing connected by yielding means forming a connection between themotor-support and the front member and adapted to confine the vibrationof the motor to the rear member.

9. Amotor-cycle framehavingafront member provided with a seat-postsupported by the crank-bracket and a rear member having its fork endsconnected by bars to a cross-bar adapted to form a motor-support, thefront and rear members being connected by yielding means forminga'connection between the motor-support and the seat-post at the top andthe motor-support and the crank-bracket at the bottom and adapted toconfine the vibration of the motor to the rear member.

In Witness whereof I have hereunto signed my name in the presence oftwosubscribing witnesses.
